Milking system with detection system

A milking system, comprising:

• a milker including a milking control device;
• a milk line in fluid connection with the milking device;
• and
• a sampling and analysis device arranged to take a sample of the milk from the milk line and to analyze the sample,
• wherein the milking control device is arranged to control management of the dairy animal based on a result of said analysis pf the sample,
• wherein the sampling and analysis device comprises:
• a control unit for controlling the sampling and analysis device;
• a sample supply line connected to the milk line and arranged to receive, under the control of the control unit, said sample from the milk line;
• a pump device arranged to control the flow of the sample;
• a cassette comprising:
• a first liquid connector;
• a sample receiving line releasably connected to the sample supply line by the firsty liquid connector in the cassette, the sample receiving line being arranged to receive the sample from the sample supply line;
• a tape reel and a tape wound on said tape reel, the tape comprising a base tape layer to which is provided a series of separate reagent pads arranged to provide a detectable response in the presence of at least one substance;
• and
• a dosing device controlled by the control unit and arranged to provide a droplet of the sample onto a reagent pad of the series of separate reagent pads, the dosing device comprising a nozzle in fluid connection with the sample receiving line, and a nozzle mover arranged to move the nozzle in at least a longitudinal direction;
• wherein the sampling and analysis device comprises a tape mover arranged to move and unwind the tape from the tape reel, under the control of the control device;
• an optical radiation source for emitting optical radiation;
• an optical sensor device arranged to detect optical radiation coming from the reagent pad supplied with said droplet of the sample, and to analyze the detected optical radiation to provide an indication of a presence or a concentration of said at least one substance in said droplet, droplet;
• and
• a pump drive, external to the cassette, and releasably operably connected to the pump device for driving the pump device,
• wherein the cassette is replaceably received in the milking system.
